Abstract: When data about plural book sheets, each belonging to one of plural chapters, are edited to bind the plural book sheets by a casing-in operation in such a manner that chapter range images, which indicate the respective ranges of the plural chapters, are displayed on an edge so that the chapter range images that are adjacent to each other are arranged at different positions from each other in the top-bottom direction, a marker image emphasizing the chapter range image is adjacent to the chapter range image indicating the range of a chapter having book sheets the number of which is less than or equal to a predetermined threshold.

Abstract: A preview screen display control apparatus includes: a print data generating section that receives image data and generates print data which is capable of being discriminated by a printing apparatus, based on the image data; a print data transmitting section that communicates with the printing apparatus, receives the print data output from the print data generating section, and outputs the print data to the printing apparatus; and a preview screen display control section that displays a preview screen based on the print data generated by the print data generating section. The print data transmitting section is configured to output a control signal that causes the preview screen display control section to initiate operations, and the preview screen display control section is configured to initiate operations based on the control signal output by the print data transmitting section to display the preview screen.
